Figure 4-1 Catalyst RSM/VIP2-15 or Catalyst RSM/VIP2-40 with One-Port PA-T3 Serial
Port Adapters in Port Adapter Slots 0 and 1
Note Port adapters have a handle attached, but this handle is not shown to allow a full view of detail
on each port adapter’s faceplate.
Depending on the circumstances, you might need to install a new port adapter on a
Catalyst RSM/VIP2 motherboard or replace a failed port adapter in thefield. In either case, you need
a number 1 Phillips screwdriver, an antistatic mat on which you can place the removed interface
processor, and an antistatic container in which you can place a failed port adapter for shipment back
to the factory.
Caution To prevent system problems, do not remove port adapters from the Catalyst RSM/VIP2
motherboard or attempt to install other port adapters on the Catalyst RSM/VIP2 motherboard while
the system is operating. To install or replaceport adapters, first remove theCatalyst RSM/VIP2 from
the chassis.
Note Each port adapter circuit board is mounted to a metal carrier and is sensitive to ESD damage.
The following procedures should be performed by a Cisco-certified service provider only. The
Catalyst RSM/VIP2 supports online insertion and removal (OIR), but individual port adapters do
not. To replace port adapters, you must first remove the Catalyst RSM/VIP2 from the chassis and
then install or replace port adapters as required. If a blank port adapter is installed on the Catalyst
RSM/VIP2 in which you want to install a new port adapter, you must first remove the Catalyst
RSM/VIP2 from the chassis and then remove the blank port adapter.
